How Apple Watch will be your digital wallet... and keychain

Information broker. Health tracker. Digital wallet and keys. Communicator. Remote Control. We might not have gotten it presented on stage like that, but we still got it it's all one product. It's the Apple Watch.

One of the things that will likely be compelling to many is Apple Watch as digital wallet and keychain. We've seen Apple Pay already, but when it comes to authentication, there's a lot more to see.
